The area of unshaded portion in the figure (C )216 is the correct option.
Step-by-step explanation:
Given figure,
Side of square = 21 cm
∴ Side of square = 21 × 21
= 441
Side of one small square = cm
∴ Area of one small square = 3 × 3 = 9
∴ Area of one unshaded region = (3 + 2 + 1) × 9 = 54
Area of unshaded region = 54 × 4
= 216
Hence, the area of unshaded portion in the figure (C )216 is the correct option.
